. Specification of Letters Patent. Application filed March 8, 1909. Serial No. 481,943.

Patented July 13, 1909.

To all whom it may concern:

Be it known that I, WILLIA J HERALD, a subject of the King of Great Britain, and reworth and Province of Ontario, Canada, have invented. new and useful Improvements in YVire Lathing, of which the following is a specification. I

The objects of my invention are, first, to provide a wire lathing adapted'to be secured ground for plaster, second, to provide a wire lathing which. is of a truss form and construction, thereby afiording inherent rigidity and stiffness, and third, to provide a wire lathing adapted to receive a coating or coatings of and to retain thesame in .a rigi I attain these objects by the device illustrated in the accompanying drawing, in which:

Figure lathing,

1 is a face view of the woven wire the edges being broken, and the bottom. Fi 2 is an enlarged sectional view of the athing through the transverse broken'line, 1, 1, Fig. 1. Fig. 3 is an enlarged sectionalv 'ew of the cloth through the transverse broken line, 2, .2, Fig. 1. Fig. 4 is an enlarged sectional side view of the cloth through the vertical broken line 3, 3, Fig. 1 as viewed from the left hand side In the drawing the warp wires which eX- tend lengthwise in the weaving, are indicated b A, and are a proper distance apart, para el'with each other, and on one plane. Across the warp wires A, and at right angles therewith, are weft wires 0 and D arranged alternately on opposite sides of the warp wires, and parallel with each other. All the weft wires 0 are on one: side of the war wires A, and on the same lane with eacother, and all the weft wires are on the o posite side of the said warpwires, and on t e same plane with each other. The alternate weft Wires C and D are parallelwitheach other, and-at right angles to the warp wires A, l A lesser wire B follows the warp wire A,

weft wiresC and D, and crossing alternately the warp wires A, binding the intersecting buckling, and

formation thereby preventing and affording and as rigid and em I strength, stability and rigidity for the purpose intended.

The component parts of this lathing are preferably made of steel wire. The lathing is made the standard width and of any length, and the side ed es are finished by any well known metho in wire weaving.

It will be noticed that the warp wires A are perfectly-straight and on one plane, also that the weft wires C on one side of the warp wires are on one plane, and the weft wires D, are

in alternate order to theweft wires 0, and

are also perfectly straight on the opposite side of the warp wires A, thereby producing a minimum of deflection of the said straight wires, as .a result. The lighter binding d wires B, take all the crimp of the lathingg were the said wires B and the warp wires A of the same diameter, then said wires A and B would be both equally crimped, or corrugated and therefore not the purpose nor object of this invention. r k

The construction of the lathing with the bod of straight wires, as shown and set fort is purposel thickness to the latliing thereby producing a truss formation and a pronounced rigid lathing, having practically unyielding The method of construction is suc that a light binding wire B is purposely selected in order to take all the crimp of the lathing in itself, to produce the maximum thickness of. lathing, thereby correspondingly increasing the rigidity. It is obvious, in wire lathing comprising corrugated, or crimped wires over and under each other, and in spiral form, or double spiral form, as the case may be, that the maximum of thickness can not be attained, neither can a lathing) be produced as thic odymg a truss formation, by the same amount of material, as is set forth in my'inventi on. 1

What I claim as In invention and desire to secure by Letters atent, is

1 r A wire lathing com rising straight parallel warp wires on one'p' fane, strai httransverse parallel weft wires arranged a tcrnatel on the opposite sides of the warp wires, eac side on one plane, a lesser'wire following in contiguity each warp wire and passing alternatel over and crossing alternately the warp wire and possensing inherent resiliency to receive all the to give a maximum ualities. j

under the weft wires and.

crimp, thereby binding the intersecting parts together in truss formation.

2. A Wire lathing comprising straightwarp wires on one plane and parallel one with the other, straight transverse wires on one side of the warp wires on one plane and parallel. one with the other, weft wires arranged alterthereby'binding the intersecting parts of the warp and the weft wires together.

3. A wire lathing comprising straight pareaame allel warp Wires on the same plane, straight transverse parallel weft wires .on the warp and parallel with one another, a lesser wire,

following each straight warp wire and in contiguity therewith, and passing alternately over and under the straight weft wires and crossing alternately the straight warp wires in crimped succession thereby bindlng the weft wires on the opposite sides of the warp Wire to said warp Wire in truss formation.
